This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.
Inserts or deletes ActivatedRule objects in a WebACL. Each Rule identifies web requests that you want to allow, block, or count. When you update a WebACL, you specify the following values:
-
A default action for the
WebACL, eitherALLOWorBLOCK. AWS WAF performs the default action if a request doesn't match the criteria in any of theRulesin aWebACL. -
The
Rulesthat you want to add or delete. If you want to replace oneRulewith another, you delete the existingRuleand add the new one. -
For each
Rule, whether you want AWS WAF to allow requests, block requests, or count requests that match the conditions in theRule. -
The order in which you want AWS WAF to evaluate the
Rulesin aWebACL. If you add more than oneRuleto aWebACL, AWS WAF evaluates each request against theRulesin order based on the value ofPriority. (TheRulethat has the lowest value forPriorityis evaluated first.) When a web request matches all the predicates (such asByteMatchSetsandIPSets) in aRule, AWS WAF immediately takes the corresponding action, allow or block, and doesn't evaluate the request against the remainingRulesin theWebACL, if any.
To create and configure a WebACL, perform the following steps:
-
Create and update the predicates that you want to include in
Rules. For more information, see CreateByteMatchSet, UpdateByteMatchSet, CreateIPSet, UpdateIPSet, CreateSqlInjectionMatchSet, and UpdateSqlInjectionMatchSet. -
Create and update the
Rulesthat you want to include in theWebACL. For more information, see CreateRule and UpdateRule. -
Create a
WebACL. See CreateWebACL. -
Use
GetChangeTokento get the change token that you provide in theChangeTokenparameter of an UpdateWebACL request. -
Submit an
UpdateWebACLrequest to specify theRulesthat you want to include in theWebACL, to specify the default action, and to associate theWebACLwith a CloudFront distribution.The
ActivatedRulecan be a rule group. If you specify a rule group as yourActivatedRule, you can exclude specific rules from that rule group.If you already have a rule group associated with a web ACL and want to submit an
UpdateWebACLrequest to exclude certain rules from that rule group, you must first remove the rule group from the web ACL, the re-insert it again, specifying the excluded rules. For details, see ActivatedRule$ExcludedRules .
Be aware that if you try to add a RATE_BASED rule to a web ACL without setting the rule type when first creating the rule, the UpdateWebACL request will fail because the request tries to add a REGULAR rule (the default rule type) with the specified ID, which does not exist.
For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.
Parameters:
-
web_acl_id(ResourceId) –The
WebACLIdof the WebACL that you want to update.WebACLIdis returned by CreateWebACL and by ListWebACLs. -
change_token(ChangeToken) –The value returned by the most recent call to GetChangeToken.
-
updates(Optional[WebACLUpdates], default:None) –An array of updates to make to the WebACL.
An array of
WebACLUpdateobjects that you want to insert into or delete from a WebACL. For more information, see the applicable data types:-
WebACLUpdate: Contains
ActionandActivatedRule -
ActivatedRule: Contains
Action,OverrideAction,Priority,RuleId, andType.ActivatedRule|OverrideActionapplies only when updating or adding aRuleGroupto aWebACL. In this case, you do not useActivatedRule|Action. For all other update requests,ActivatedRule|Actionis used instead ofActivatedRule|OverrideAction. -
WafAction: Contains
Type
-
-
default_action(Optional[WafAction], default:None) –A default action for the web ACL, either ALLOW or BLOCK. AWS WAF performs the default action if a request doesn't match the criteria in any of the rules in a web ACL.
Raises:
-
WAFInternalErrorException–The operation failed because of a system problem, even though the request was valid. Retry your request.
-
WAFInvalidAccountException–The operation failed because you tried to create, update, or delete an object by using an invalid account identifier.
-
WAFInvalidOperationException–The operation failed because there was nothing to do. For example:
-
You tried to remove a
Rulefrom aWebACL, but theRuleisn't in the specifiedWebACL. -
You tried to remove an IP address from an
IPSet, but the IP address isn't in the specifiedIPSet. -
You tried to remove a
ByteMatchTuplefrom aByteMatchSet, but theByteMatchTupleisn't in the specifiedWebACL. -
You tried to add a
Ruleto aWebACL, but theRulealready exists in the specifiedWebACL. -
You tried to add a
ByteMatchTupleto aByteMatchSet, but theByteMatchTuplealready exists in the specifiedWebACL.
-
-
WAFInvalidParameterException–The operation failed because AWS WAF didn't recognize a parameter in the request. For example:
-
You specified an invalid parameter name.
-
You specified an invalid value.
-
You tried to update an object (
ByteMatchSet,IPSet,Rule, orWebACL) using an action other thanINSERTorDELETE. -
You tried to create a
WebACLwith aDefaultActionTypeother thanALLOW,BLOCK, orCOUNT. -
You tried to create a
RateBasedRulewith aRateKeyvalue other thanIP. -
You tried to update a
WebACLwith aWafActionTypeother thanALLOW,BLOCK, orCOUNT. -
You tried to update a
ByteMatchSetwith aFieldToMatchTypeother than HEADER, METHOD, QUERY_STRING, URI, or BODY. -
You tried to update a
ByteMatchSetwith aFieldofHEADERbut no value forData. -
Your request references an ARN that is malformed, or corresponds to a resource with which a web ACL cannot be associated.
-
-
WAFLimitsExceededException–The operation exceeds a resource limit, for example, the maximum number of
WebACLobjects that you can create for an AWS account. For more information, see Limits in the AWS WAF Developer Guide. -
WAFNonexistentContainerException–The operation failed because you tried to add an object to or delete an object from another object that doesn't exist. For example:
-
You tried to add a
Ruleto or delete aRulefrom aWebACLthat doesn't exist. -
You tried to add a
ByteMatchSetto or delete aByteMatchSetfrom aRulethat doesn't exist. -
You tried to add an IP address to or delete an IP address from an
IPSetthat doesn't exist. -
You tried to add a
ByteMatchTupleto or delete aByteMatchTuplefrom aByteMatchSetthat doesn't exist.
-
-
WAFNonexistentItemException–The operation failed because the referenced object doesn't exist.
-
WAFReferencedItemException–The operation failed because you tried to delete an object that is still in use. For example:
-
You tried to delete a
ByteMatchSetthat is still referenced by aRule. -
You tried to delete a
Rulethat is still referenced by aWebACL.
-
-
WAFStaleDataException–The operation failed because you tried to create, update, or delete an object by using a change token that has already been used.
-
WAFSubscriptionNotFoundException–The specified subscription does not exist.
-
UnknownServiceError–The service returned an error code this client does not model.

To update a Web ACL The following example deletes an ActivatedRule object in a WebACL with the ID webacl-1472061481310.
>>> client.update_web_acl(web_acl_id='webacl-1472061481310', change_token='abcd12f2-46da-4fdb-b8d5-fbd4c466928f', updates=[{'Action': 'DELETE', 'ActivatedRule': {'Action': {'Type': 'ALLOW'}, 'Priority': 1, 'RuleId': 'WAFRule-1-Example'}}], default_action={'Type': 'ALLOW'})
